Case Study

Poly(vinylidene fluoride) for the Fabrication of Electroactive PVDF/Magnetic Nanoparticle Composites for Deformation Sensing

Martins LA, et al. Polymer, 2025, 340, 129278.

Poly(vinylidene fluoride) (PVDF) membranes were engineered with cobalt ferrite (CFO) and iron magnetite (FE) nanoparticles (10 wt%) via non-solvent induced phase separation (NIPS) and subsequent mechanical compression. PVDF was dissolved in DMF at 60 °C, while magnetic particles were pre-dispersed by 4 h ultrasonication. The polymer-particle solution was cast onto glass substrates (750 μm thickness) and precipitated in ethanol, followed by washing in ultrapure water and vacuum drying. Mechanical compression yielded compacted membranes with reduced porosity and enhanced β-phase content, resulting in improved piezoelectric response. Crystallinity decreased slightly, but the electroactive structures were maximized. This approach demonstrates the practical application of PVDF in high-performance deformation sensing devices, where the combination of magnetic nanoparticles and mechanical compaction enables tunable electromechanical properties.

Poly(vinylidene fluoride) for Solid Polymer Electrolytes in Room-Temperature Lithium-Ion Batteries

Macedo VM, et al. Journal of Power Sources, 2025, 657, 238138.

Poly(vinylidene fluoride) (PVDF) was employed to fabricate solid polymer electrolytes incorporating UiO-66 metal-organic frameworks (MOF) loaded with a protic ionic liquid (IL). MOF@IL mixtures were ultrasonicated in DMF for 3 h at room temperature before adding PVDF under magnetic stirring until complete dissolution (~3 h). Films were cast using the doctor-blade method (1000 μm gap) and thermally treated at 210 °C for 10 min. Variation of IL loading in MOF pore space allowed optimization of ionic conductivity and lithium transference number. The composite exhibited stable charge/discharge performance, with the best results at a 20/60 MOF/IL ratio (ionic conductivity 4.91 × 10-4 S cm⁻¹ at RT). This experimental approach highlights PVDF's utility in solid-state electrolytes, where polymer-MOF-IL integration enhances structural stability and electrochemical performance.
